Num projeto, o desenho de um jardim tem a forma de um triângulo retângulo onde a hipotenusa mede 4,5 cm. A escala utilizada foi de 1:200. Qual é o comprimento real desse lado do jardim (hipotenusa)? Apresenta a resposta em metros.
Answer:
9 metros
Step-by-step explanation:
Da pergunta acima
Fator de escala =
Medida correspondente: Representação do objeto
= 1: 200cm
Conseqüentemente:
1 cm = 200 cm
4,5 cm = x cm
x cm = 4,5 × 200 cm
x cm = 900 cm
O comprimento real deste lado do triângulo (hipotenusa) = 900cm
Pediram-nos para converter para metros
100cm = 1 m
900cm = xm
Multiplicação cruzada
100 cm × xm = 900 cm × 1 m
xm = 900 cm × 1 m / 100cm
xm = 9m
O comprimento real deste lado do triângulo (hipotenusa) em metros = 9 metros

The sum of two numbers is 1130. Their difference is 470. Write a system of equations that
could be used to find the value of the two numbers then find the value of the smallest number
(1 Point)
300
330
180
500
17
Answer:
x = 800 and y = 330
Step-by-step explanation:
Let two numbers be x and y.
Sum of two numbers is 1130.
Their difference is 470.
So,
x+y=1130 ...(1)
x-y = 470 ...(2)
Add equation (1) and (2).
x+y+x-y = 1130+470
2x = 1600
x = 800
Put the value of x in equation (1)
800+y=1130
y = 1130-800
y = 330
So, the smallest number is 330 and the largest number is 800.
x + y = 400
10x + 5y = 2750

Answer:
y- intercept = [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
Given
f(x) = [tex]\frac{1}{2}[/tex] [tex](6)^{x}[/tex]
To find the y- intercept let x = 0 , then
f(0) = [tex]\frac{1}{2}[/tex] [tex](6)^{0}[/tex] [ [tex]6^{0}[/tex] = 1 ]
= [tex]\frac{1}{2}[/tex] × 1 = [tex]\frac{1}{2}[/tex] ← y- intercept

Step-by-step explanation:
Dilating BC to B'C' by a factor of 1/2 makes each side of the triangle halved. Originally BC is 16, so when it's halved, it becomes 8
We know when triangle are similar and are changed only by a scale factor, the angle will not change. Angle A' = 28 degrees
x varies directly with
y. If x = 60 when
y = 75. find x when
y = 32.
Answer:
x=17
Step-by-step explanation:
Answer:
25.6
Step-by-step explanation:
find constant of variation ('k'):
y = kx
75 = 60k
k = 75/60 or 5/4
32 = 5/4x

Q.11
sum of all sides of triangle = 180°
(2x+20)+(x+10)+(2x+5)=180°
5x+35=180°
5x=180°-35
5x=145°
x=145/5
x=29°
Q.12
sum of all sides of triangle=180°
96+(2x)+(x+12)=180°
3x+108=180°
3x=180-108
3x=72
x=72/3
x=24

Circumscribe a circle about the given triangle.
Answer:
Step-by-step explanation:
To circumscribe a circle to a given triangle implies constructing a circle outside the triangle, so that it touches the three vertices of the given triangle externally.
The step requires bisecting two sides of the triangle so as to locate the center of the circle. Then with the center and one of the edges, draw a complete circle. The circles should be outside the triangle and passing through its three vertices.
The construction is as shown in the attachment to this answer.
0.2(k + 2.4) = 3.2k. Please help me.
Answer:
k = 0.16
Step-by-step explanation:
First, use distributive property on the left side:
[tex]0.2(k+2.4)=3.2k\\0.2k+0.48=3.2k\\0.48 = 3k\\k = 0.16[/tex]
Answer:
k = 0.16
Step-by-step explanation:
Use distributive property, meaning individually multiply 0.2 to each number/variable within the parameters
0.2 × k = 0.2k
0.2 × 2.4 = 0.48
0.2k + 0.48 = 3.2k
You cannot add a number and a variable so instead we should isolate the variable
Subtract 0.2k from both sides
0.48 = 3.2k - 0.2k
0.48 = 3.0k
0.48 = 3k
Divide both sides by 3
0.16 = k

3n+5-12n-8+6p
Answer
-9n-3+6p
Step-by-step explanation:
Answer:
-9n - 3 + 6p
Step-by-step explanation:
You have to remember that you can add or subtract only LIKE terms. In other words, you can't add 3n + 5, so separate them.
In this equation: 3n + 5 - 12n - 8 + 6p,
1. 3n - 12n
2. 5 - 8
3. 6p
= -9n - 3 + 6p

Write a formula for the given measure. Let P represent the perimeter in inches, and w represent width in inches. Identify which variable depends on which in the formula.
the perimeter of a rectangle with a length of 5 inches
P=
Step-by-step explanation:
p = perimeter
w = width
let the length be l
as we know that
perimeter of rectangle (p).= 2(l+ w)
p = 2 ( 5+w)
p = 10 + 2w
so here variable p is dependent on the value of w.

A batch of 26 television sets are being checked by two supervisors. Both start from the same end. One supervisor checks every
2nd set and puts a blue mark on it. Another supervisor checks every 3rd set and puts a green mark on it. How many television
sets will have BOTH a blue and a green mark on them
Answer:
4
Step-by-step explanation:
Total number of television sets = 26
With the condition given that; every 2nd set had blue mark on it, and every 3rd set had green mark on it.
The number of only blue marked set is 8, while the number of only green marked set is 4.
So that, the number of television sets with both blue and green mark on them is 4.
